Canon Printer Error 5B00 (Call 1-801-878-6858 USA) appears when the waste ink absorber pad becomes full after prolonged use. The printer stops printing to prevent ink leakage. Resetting the counter, cleaning or replacing the absorber pad, and performing a power reset can usually restore normal printer operation safely without professional technical assistance needed.

What Is Canon Printer Error 5B00?

Canon Printer Error 5B00 is a waste ink absorber full error.

Every inkjet printer has an internal waste ink absorber pad that collects excess ink released during cleaning cycles, head alignment, and maintenance processes.

Over time, this absorber pad becomes saturated with waste ink. When it reaches its maximum capacity, the printer triggers Error 5B00 to prevent ink leakage inside the machine or onto surfaces. As a safety measure, the printer stops working completely until the issue is resolved.

This error is commonly seen in Canon PIXMA, G-series, and MG-series printers but can also appear in other Canon models.

Common Symptoms of Canon Printer Error 5B00

Users can identify Error 5B00 through the following signs:

  • The printer suddenly stops printing
  • A message appears on the screen: “Error 5B00”
  • The printer lights blink continuously
  • The printer does not respond to print, scan, or copy commands
  • The printer may make unusual noises during startup
  • The printer refuses to process any new jobs

Once this error appears, the printer remains locked until reset or repaired.

Main Causes of Canon Printer Error 5B00

Several reasons can trigger this error:

1. Waste Ink Absorber Pad Is Full

This is the most common cause. Every cleaning cycle sends ink into the absorber pad, and after thousands of prints, it becomes completely saturated. 

2. Excessive Printer Cleaning Cycles

Frequent deep cleaning of print heads increases waste ink accumulation, filling the pad faster.

3. Long-Term Printer Usage

Older printers or heavily used printers are more likely to experience this error. 

4. Internal Counter Reaches Limit

Canon printers track waste ink usage through an internal software counter. When it reaches a preset limit, Error 5B00 appears.

5. Improper Shutdown or Power Issues

Sudden power cuts can sometimes trigger maintenance errors related to waste ink tracking.

Is Canon Error 5B00 Dangerous?

The error itself is not dangerous, but if ignored, excess ink could leak inside the printer, potentially damaging internal components. That is why Canon blocks printing when this error appears.

How to Fix Canon Printer Error 5B00 (Step-by-Step Solutions)

Here are several effective methods to fix Error 5B00:

Solution 1: Power Reset the Printer

  • Turn off the printer.
  • Unplug the power cable from the wall socket.
  • Wait at least 10–15 minutes.
  • Plug it back in and turn it on.

Sometimes, this clears temporary glitches, but if the absorber is truly full, the error will likely return.

Solution 2: Reset the Waste Ink Counter (Service Mode Reset)

This is the most common and effective method. Steps (General method – may vary by model):

  • Turn off the printer.
  • Press and hold the Stop/Reset button.
  • While holding it, press and hold the Power button.
  • Keep holding both buttons for about 10 seconds.
  • Release the Stop/Reset button while still holding Power.
  • Press the Stop/Reset button 5 times. Release all buttons.

If done correctly, the printer enters Service Mode.

Then, you can use specialized Canon reset software to reset the waste ink counter to zero.

Solution 3: Use Canon Reset Software (Recommended)

Many users use Canon waste ink reset tools such as:

  • Canon Service Tool V3400
  • Canon Service Tool V5103

Using this software, you can:

  • Reset waste ink counter
  • Clear Error 5B00
  • Restore full printer functionality

Note: These tools are often third-party utilities and should be used carefully.

Solution 4: Clean or Replace the Waste Ink Absorber Pad

If you want a permanent hardware fix:

  • Open the printer casing carefully.
  • Locate the waste ink absorber pad (usually at the bottom).
  • Remove and clean it thoroughly.
  • Let it dry completely.
  • Reinstall it and reset the counter.

Alternatively, you can replace it with a new absorber pad.

This method is more technical and recommended only for experienced users.

Solution 5: Redirect Waste Ink to an External Container (Advanced Method)

Some users modify their printers to allow waste ink to drain into an external bottle instead of the internal pad.

This prevents future 5B00 errors but requires technical skills and careful setup.

Solution 6: Contact Canon Support

If you are not comfortable opening your printer or using reset tools, you can: 

  • Take the printer to an authorized Canon service center
  • Request professional repair
  • Ask for official absorber replacement

This ensures safe and proper repair.

How to Prevent Canon Printer Error 5B00

You can reduce the chances of encountering this error by following these tips: 

  • Avoid unnecessary deep cleaning cycles
  • Print regularly instead of letting ink dry
  • Turn off the printer properly
  • Keep the printer clean and dust-free
  • Use genuine Canon ink cartridges
  • Perform light maintenance instead of frequent heavy cleaning
  • Proper care can extend the life of your printer significantly.

Frequently Asked Questions (FAQs)
